Question

Which of the following steps are necessary to solve C=59(F+32) for Fahrenheit if the temperature is 45∘Celsius? Select all that apply.

Answer 1

Answer:$\begin{gathered} \frac{9}{5}C=(F+32) \\ \\ \frac{9}{5}C-32=F \end{gathered}$Explanation:

The given equation is:

$C=\frac{5}{9}(F+32)$

Multiply both sides by 9/5

$\begin{gathered} \frac{9}{5}C=(\frac{9}{5})(\frac{5}{9})(F+32) \\ \\ \frac{9}{5}C=F+32 \end{gathered}$

Subtract 32 from both sides

$\begin{gathered} \frac{9}{5}C-32=F+32-32 \\ \\ \frac{9}{5}C-32=F \end{gathered}$
